Vuorinen, R. The concept of adaptation‐level in psychological research. Scand. J. Psychol., 1973, 14, 228–240.‐ Helson's adaptation‐level theory (ALT) is appraised as a general theory of psychology. The reformulated Fechner law underlying ALT is shown to be untenable and the conceptual status of AL is shown to be self‐contradictory. The ambiguous measures and the inconsistent theoretical definitions proposed for AL are found to limit the scope of ALT. Reasons for its flexibility and claimed heuristic value are analyzed and potential sources of confusion are suggested. Some defects of ALT are likely to be shared by other behaviouristic theories since they follow from a commitment to the strict S‐R model.

“…However, AL theory was challenged by Stevens's (1958) ideas that context effect reflect modulations at the response stage rather than at the perceptual stage. Ellis (1972) later proposed a multifactor theory taking into account possible alterations at both the sensory and response levels.…”

To further explore how memory influences time judgments, we conducted two experiments on the lifespan of temporal representations in memory. Penney et al (2000, Journal of Experimental Psychology Human Perception and Performance 26 1770-1787) reported that the perceived duration of auditorily and visually marked intervals differs only when both marker-type intervals are compared directly. This finding can be explained by a 'memory-mixing' process, whereby the memory trace of previous intervals influences the perception of upcoming ones, which are then added to the memory content. In the experiments discussed here, we manipulated the mixing mode of auditory/visual signal presentations. In experiment 1, signals from the same modality were either grouped by blocks or randomised within blocks. The results showed that the auditory/visual difference decreased but remained present when modalities were grouped by blocks. In experiment 2, we used a line-segmentation task. The results showed that, after a training block was performed in one modality, the perceived duration of signals from the other modality was distorted for at least 30 trials and that the magnitude of the difference decreased as the block went on. The results of both experiments highlight the influence of memory on time judgments, providing empirical support to, and quantitative portrayal of, the memory-mixing process.

“…This effect also occurs for cross-modal matches (Ward, 1975). In other paradigms the opposite effect, contrast, has prevailed (Helson, 1964; Ellis, 1972). McKenna (1984) has examined the differential conditions under which these two opposite context effects occur.…”

The ‘new psychophysics' is reviewed in terms of four issues: (1) the adequacy of the power law as an empirical description, (2) the validity of this law, (3) what is being measured and (4) the theoretical implications of the power law. Each issue is considered in turn with an emphasis on the theoretical implications since it is thought that this approach to psychophysical judgement can best be assessed in this respect. It is found that there are critical weaknesses in this approach to psychophysics.
